title: First description of qnrS1-IncN plasmid in a ST11 Salmonella Enteritidis clinical isolate from Portugal.
abstract: The presence of qnr and qepA genes was investigated among 300 nontyphoidal Salmonella showing decreased susceptibility to ciprofloxacin obtained from different sources in Portugal (2002-2004). The qnrS1 gene was located within a conjugative IncN plasmid in a ST11 Salmonella Enteritidis strain from human origin, a serotype commonly implicated in human infections and frequently encountered in poultry.
